Storing large blobs in a "WITHOUT ROWID" table turns out to be extremely
slow when the tree must be rebalanced.
* Split out keystore capability into separate interface, making each
keystore a separate instance
* Disable "WITHOUT ROWID" optimization by default
* Implement prefix lookup that allows iterating over all values with a
certain prefix in their key
* Fix raw Exceptions in hexary caused by forward declarations
* Fix raw Exceptions in trie/db caused by forward declarations
* And now we can remove those db Proc CatchableError raises
`les_protocol.nim` failed to build, due to very silly Nim bugs
nim-lang/Nim#8792 and nim-lang/Nim#17102.
import
../../[rlp, keys], ../../common/eth_types,
../[rlpx, kademlia, blockchain_utils], ../private/p2p_types,
The silly part is `../` has to be quoted if it's before a group of files, but
not before a single file. Most places in PR #344 / 7624153 use the workaround
`".."/` but it was missed in `les_protocol.nim`:
nimbus-eth1/vendor/nim-eth/eth/p2p/rlpx_protocols/les_protocol.nim(14, 3)
Error: cannot open file: ../../[rlp,keys]

It's been confirmed that the test fails if the Kademlia crash workaround isn't
in `findNode`, and passes with it there.

When using discv4 (Kademlia) to find peers, there is a crash after a few
minutes. It occurs for most of us on Eth1 mainnet, and everyone on Ropsten.
The cause is `findNodes` being called twice in succession to the same peer,
within about 5 seconds of each other. ("About" 5 seconds, because Chronos does
not guarantee to run the timeout branch at a particular time, due to queuing
and clock reading delays.)
Then `findNodes` sends a duplicate message to the peer and calls
`waitNeighbours` to listen for the reply. There's already a `waitNeighbours`
callback in a shared table, so that function hits an assert failure.
Ignoring the assert would be wrong as it would break timeout logic, and sending
`FindNodes` twice in rapid succession also makes us a bad peer.
As a simple workaround, just skip `findNodes` in this state and return a fake
empty `Neighbours` reply. This is a bit of a hack as `findNodes` should not be
called like this; there's a logic error at a higher level. But it works.
Tested for about 4 days constant operation on Ropsten. The crash which occured
every few minutes no longer occurs, and discv4 keeps working.

* Add search for best route and refactor setupNat to setupAddress
* Update setupAddress and make enr ports in discovery optional
* Add specific error log when no route is found
* Use bindIP if it is public
* Adjust some log levels
